包路径：org.apache.tools.ant.util.FileUtils
类名称：FileUtils

FileUtils介绍

[英]This class also encapsulates methods which allow Files to be referred to using abstract path names which are translated to native system file paths at runtime as well as copying files or setting their last modification time.
[中]此类还封装了一些方法，这些方法允许使用抽象路径名引用文件，这些抽象路径名在运行时转换为本机系统文件路径，还可以复制文件或设置其上次修改时间。
